On Saturday, Martin sent an email to Udall supporters advertising
a contest where donors who give a $5 contribution can win a
ticket to the fundraiser. The message included a reference to the
murderous wedding ceremony depicted in one of the most infamous
episodes of the "Game of Thrones" television series.

"I know what you’re thinking: A party with George R.R. Martin
sounds a bit dubious. Don’t worry -- no funny business, no
minstrels, and no weddings. I promise," Martin wrote. "In fact,
we’ll even pick up your airfare and hotel. Your only job is to
show up and be ready to chat with me and Tom."

This isn't the first time Martin has expressed an interest in
politics. He previously indicated his support for President
Barack Obama and other Democratic politicians in posts on his
blog during the 2012 election.

Subject: See you soon?

Hi Friend,

This is George R.R. Martin. You may know me for my book
series A Song of Ice and Fire. Or you may have seen the TV
show Game of Thrones.

But I’m also New Mexican and a proud supporter of my
friend Senator Tom Udall.

So when Tom told me that he was going to be in my hometown of
Santa Fe on October 7th, I decided I’d throw him a
little party at my personal theatre. Of course, no party is
complete without guests -- which is where you come in.
